The Nonadditive Generalization of Klimontovich's S-Theorem for Open Systems and Boltzmann's Orthodes: We show that the nonadditive open systems can be studied in a consistent manner by using a generalized version of S-theorem. This new generalized S-theorem can further be considered as an indication of self-organization in nonadditive open systems as prescribed by Haken. The nonadditive S-theorem is then illustrated by using the modified Van der Pol oscillator. Finally, Tsallis entropy as an equilibrium entropy is studied by using Boltzmann's method of orthodes. This part of dissertation shows that Tsallis ensemble is on equal footing with the microcanonical, canonical and grand canonical ensembles. However, the associated entropy turns out to be Renyi entropy.
Solo lyra viol music of Tobias Hume (c. 1579-1645): Historical context and transcription for modern guitar.: The seventeenth century in England produced a large and historically significant body of music for the viola da gamba played "lyra-way." Broadly defined, playing "lyra-way" on the viol meant playing from tablature notation in a polyphonic style. Most players of plucked strings such as lute and guitar are familiar with tablature and, as a result, have a decisive advantage when attempting to explore this music. Other factors that make lyra viol repertory potentially attractive to the modern guitarist are its chordal textures, similarities in physical properties of the instruments, and many points of connection regarding the principles of left hand technique. The purpose of this study is two-fold: 1) to illuminate the historical and cultural context of the seventeenth-century English lyra viol music in general and that of Tobias Hume (c. 1579-1645) in particular; and 2) to present an idiomatic transcription for the modern guitar of four representative pieces from Hume's 1605 collection Musicall Humours. Musicall Humours, published in London in 1605, is one of the first and most significant collections of music for the lyra viol. The collection is both ambitious and groundbreaking, being the largest repertory of solo music for the lyra viol by a single composer in the early seventeenth century. Since the modern guitar, although not as contrapuntally facile as the keyboard, is nevertheless capable of executing two- or three-voice polyphony, reconstruction of the polyphonic implications of solo lyra viol music becomes the first step in creating an idiomatic arrangement. The differences in acoustical properties and technical capabilities between the viol and the modern guitar have to be taken into consideration when deciding on the degree to which harmony must be filled in. Generally, thinner textures of the lyra viol music, when transferred directly to the guitar, tend to sound incomplete. The arranger's musical sensitivity and …
Neutron Transmutation and Hydrogenation Study of Hg₁₋xCdxTe: Anomalous Hall behavior of HgCdTe refers to a "double cross-over" feature of the Hall coefficient in p-type material, or a peak in the Hall mobility or Hall coefficient in n-type material. A magnetoconductivity tensor approach was utilized to identify presence of two electrons contributing to the conduction as well as transport properties of each electron in the material. The two electron model for the mobility shows that the anomalous Hall behavior results from the competition of two electrons, one in the energy gap graded region near the CdZnTe/HgCdTe interface with large band gap and the other in the bulk of the LPE film with narrow band gap. Hg0.78Cd0.22Te samples grown by LPE on CdZnTe(111B)-oriented substrates were exposed to various doses of thermal neutrons (~1.7 x 1016 - 1.25 x 1017 /cm2) and subsequently annealed at ~220oC for ~24h in Hg saturated vapor to recover damage and reduce the presence of Hg vacancies. Extensive Magnetotransport measurements were performed on these samples. SIMS profile for impurities produced by neutron irradiation was also obtained. The purpose for this study is to investigate the influence of neutron irradiation on this material as a basis for further study on HgCdTe74Se. The result shows that total mobility is observed to decrease with increased neutron dose and can be fitted by including a mobility inverse proportional to neutron dose. Electron introduction rate of thermal neutron is much smaller than that of fission neutrons. Total recovering of the material is suggested to have longer time annealing. Using Kane's model, we also fitted carrier concentration change at low temperature by introducing a donor level with activation energy changing with temperature. Results on Se diffusion in liquid phase epitaxy (LPE) grown HgCdTe epilayers is reported. The LPE Hg0.78Cd0.22Te samples were implanted with Se of 2.0×1014/cm2 at 100keV and annealed at …
Georgy L'vovich Catoire: His Life and Music for Piano, with Special Emphasis on Poem: Second Sonata for Violin and Piano, Op. 20: A Russian composer of French descent, Georgy L'vovich Catoire (also often spelled "Katuar") (1861-1926) is one of the most neglected composers of the turn of the nineteenth and twentieth centuries. Catoire composed a number of piano pieces, most of which are chamber and solo works. These pieces are rarely studied or performed in the West. This study makes an attempt to fill this void. It thoroughly investigates Catoire's life, as well as looks into his genealogy, since his family was influential in commercial, political and cultural life of Russia for more than a hundred years. It also discusses his works for piano, with particular emphasis on Poem, Second Sonata for Violin and Piano, Op. 20. This sonata exemplifies the composer's mature style, characterized by the refinement of the harmonic and rhythmical ideas, while demonstrating melodious ingenuity and clear structural form. To date, there is no known study on this subject of such scope both in Russian and in English languages.
From Block to Traditional Schedule: The Impact on Academic Achievement, Attendance Rates, and Dropout Rates: The purpose of this study was to examine the impact of school schedule on student achievement and attendance of ninth and tenth grade students in metropolitan area Texas high schools (n = 22) and campus dropout rates. High schools that were analyzed in this study made a transition from A/B block scheduling in the 2003-04 school year to a traditional school schedule in the 2004-05 school year. Academic achievement, attendance rates and dropout rates were gathered through the archived files of the Texas Agency through the Academic Indicator of Excellence System (AEIS). Academic achievement was measured by the Texas Assessment of Knowledge and Skills (TAKS) Reading/Language Arts and Mathematics standardized tests. This study compared the mean scores of ninth grader student achievement, attendance, and dropout rates from the 2003-04 school year to the mean scores of the tenth graders from the same schools from the 2004-05 school year, after the schools converted from an A/B block schedule to a traditional class schedule. Each independent variable was divided into four subgroups; campus mean results, minority student results, limited English proficient (LEP) student results, and low-socioeconomic student results. Students under the A/B block scored significantly higher in reading achievement than when they were instructed the following year under a traditional schedule. Paired sample t-tests were conducted to analyze the data for each subgroup, and showed there was a statistically significance in reading / language arts student achievement scores for all subgroups. Statistical significance was determined with a ninety five percent confidence level (p < 0.05). Statistical analysis revealed varied results in mean scores for math academic achievement and attendance rates, but no statistical significant difference. Comparison of data showed a slight increase in mean scores for dropout rates in traditional schedule, however the results were not significant.
Snakes Alive!: On three days in March each year, the sleepy little town of Sweetwater, Texas transforms into the rattlesnake capital of the world. Snake hunters and curious tourists converge on the town of 12,000 for the Annual Sweetwater Rattlesnake Roundup. On the outside of the Nolan County Coliseum, the smell of funnel cakes and hot-dogs fills the air as vendors sell snacks and souvenirs. However the real action is inside where snakes collected from all over the state lay in piles by the thousands, waiting to be sexed, milked and ultimately killed. Through interviews and observational footage, "Snakes Alive!" explores the Sweetwater Rattlesnake Roundup, those that participate in the event, and the elements that make it an unabashed West Texas tradition.
Agreement Between Self and Other Ratings in Multi-Rater Tools: Performance, Alternative Measures, and Importance.: Multi-rater tools also referred to as 360-degree feedback tools, are frequently used in addition to traditional supervisory appraisals due to sources (i.e., supervisor, peer, direct report) unique perspectives and opportunities to view different aspects of job performance. Research has found that the differences among sources are most prevalent between self and other ratings, and the direction of agreement is related to overall job performance. Research has typically focused on one form of agreement, the direction of an individual's self-ratings compared to others' ratings. The current study expanded on past research on rater agreement using a data set (n = 215) consisting of multi-rater data for professionals participating in a leadership development process. The study examined the ability to predict job performance with three different measures of self-other agreement (i.e., difference between overall mean scores (difference), mean absolute difference across items (difference), and mean correlation across items (similarity)). The study also examined how the relationships may differ across performance dimensions. The final purpose was to explore how the importance of the performance dimensions, as rated by the participant, may moderate the relationship between self-other agreement and job performance. Partial support for study's hypotheses was found. The direction and difference measures of agreement on the overall multi-rater tool and performance dimensions accounted for a significant amount of the variance in job performance. The relationship between the similarity measure of agreement and job performance, and the moderating effect of importance were not supported in the current study.
Spanish La Junta de los Rios: The institutional Hispanicization of an Indian community along New Spain's northern frontier, 1535-1821.: Throughout the colonial period, the Spanish attempted to Hispanicize the Indians along the northern frontier of New Spain. The conquistador, the missionary, the civilian settler, and the presidial soldier all took part in this effort. At La Junta de los Rios, a fertile area inhabited by both sedentary and semi-sedentary Indians, each of these institutions played a part in fundamentally changing the region and its occupants. This research, relying primarily on published Spanish source documents, sets the effort to Hispanicize La Junta in the broader sphere of Spain's frontier policy.
Marital conflict and marital satisfaction among Latina mothers: A comparison of participants in an early intervention program and non-participants.: The purpose of the study was to better understand marital conflict and marital satisfaction among Latina mothers in the Home Instruction for Parents of Preschool Youngsters (HIPPY) program. Latina mothers living in a marriage or in a committed relationship (n = 91) reported levels of marital conflict and marital satisfaction. Between both groups, non-HIPPY mothers reported significantly less marital satisfaction and more conflict associated with affection than HIPPY mothers. A negative correlation (r = -.495, p <.001, n = 91) indicated that more satisfaction was related to less marital conflict. Out of ten marital conflicts, religion, leisure time, drinking, and other women (outside the relationship) best explained how satisfied mothers were in their relationship with their spouse. In this study, participants who were in the HIPPY program may have more support and higher marital quality. Social service programs such as HIPPY may help families build stronger marriages. Further research on Latino/Hispanic culture and values are important when developing culturally sensitive marriage and couples education.
An Interpretive Analysis of George Antheil's Sonata for Trumpet and Piano: American composer George Antheil's Sonata for Trumpet and Piano was written in 1951. This dissertation provides historical and theoretical information that gives insight into the interpretation of this sonata. Reasons why the piece deserves greater attention with respect to the standard twentieth century trumpet literature are also given. Antheil's music was influential in the development of classical music in the first half of the 20th century and, more specifically, contributed to the establishment of an American style of classical music. Composed near the end of his life, this sonata has its roots in this heritage. The understanding of Antheil's history, motivations, and compositional techniques is intended to help bring a performance of this sonata to its full potential.
Student Variables Contributing to Program Completion in Career School Sector For-Profit Schools: The general purpose of the study was to compile current descriptive information for recent graduates from career school sector institutions that reveals the significant factors which contributed to their program completion. The research project focused upon career school program completers. The scope of the study was directed to recent program completers at two career schools in Texas which offer a cross-section of programs designed to provide students specific skills for immediate employment. Based upon an extensive review of literature and the input of a focus group of experienced career school administrators and faculty members, seven variables were determined to be worthy of a focused study of their possible contributions to career school program completion. The variables were ability to accept responsibility for completion, academic preparedness, family or friends support system, self-esteem, life skills preparedness, sense of being goal-oriented, and sense of connectedness to the school. It was determined that each of the seven variables existed prominently in the majority of these recent graduates. The researcher concludes that there is a tremendous need for continued study that is focused on career school sector students. The paper offers the suggestion of a specific retention program that can be employed by career school administrators to emphasize the 7 variables and implement specific interventions designed to increase student retention and program completion.
The relationship of teacher efficacy to teacher concerns and job-embedded professional development.: As educators search for ways of improving student achievement, it is imperative that focus be placed on teacher learning and development. Currently, the trend in public schools throughout the country is to look directly at students and the deficits they bring to the learning environment when responding to those who find fault with the educational system. The current study directed attention to teachers' beliefs about their ability to affect change in student learning. The study centered on seven research questions that sought to determine: (1) the effect of job-embedded staff development on teachers' sense of efficacy; (2) the effect of job-embedded staff development on teachers' stages of concern; (3) the relationship between teacher efficacy and stages of concern; (4) the status of teachers' level of use of an innovation; and (5) the dominance of teacher concerns prior to and after involvement in job-embedded professional development. Through a mixed methodology approach, quantitative and qualitative analyses provided perspectives from 30 teachers in a suburban North Texas school district on the impact of job-embedded professional development on teacher efficacy, stages of concern, and resulting levels of use of an educational innovation. Quantitative results of two surveys: the Teacher Sense of Efficacy Scale (Tschannen-Moran & Woolfolk Hoy, 2001) and the Stages of Concern Questionnaire (Hall, George, & Rutherford, 1979) revealed a strong focus on stage 0, awareness, concerns and no statistically significant gain in teacher efficacy as teachers engaged in job-embedded professional learning. Qualitative data were gathered through Levels of Use Focused Interviews (Loucks, Newlove, & Hall, 1975) and revealed more teacher involvement with the innovation than quantitative data suggested. Further investigation into the inconsistencies between dominance of teacher concerns and perceptions of levels of use is warranted.
Computational Studies of Bonding and Phosphorescent Properties of Group 12 Oligomers and Extended Excimers.: Density functional (ca, BLYP, BPW91, B3LYP and B3PW91), MP2 and CCSD(T) methods in combination with LANL2DZ or cc-pVxZ-PP (where x=D(double), T(triple) Q(quadruple), and 5(quintuple)) basis sets have been employed in computing electronic transition energies of zinc and cadmium monomers. CCSD(T)/aug-cc-pV5Z-PP combination finds values that are 150 cm-1 from the experimental value for the zinc monomer and 240 cm-1 remove from the cadmium monomer excitation experimental value. These method/basis set combinations are also used to find spectroscopic values (re, De, we, wexe, Be , and Te) that rival experimental values for dimers and excimers. Examples of this can be seen with the CCSD(T)/aug-cc-pV5Z-PP combination phosphorescent emission results. The values found are within 120 cm-1 of the zinc emission energy and 290 cm-1 of the cadmium emission energy. While this combination rigorously models spectroscopic constants for monomers, dimers, and excimers, it does not efficiently model these constants for larger clusters with available modern computational resources. It is important to show spectroscopic trends (bonding, phosphorescent excitation and emissions) as clusters increase as the monomer and dimer emission energies do not model solid state metallophilic interactions and phosphorescence. The MP2/LANL2DZ combinations show qualitative cooperative bonding trends in group oligomers and extended excimers as size increases and shape change. Changes in excitation and emission energies are also shown as a function of size and shape of the clusters.
The Effectiveness of the Geriatric Depression Scale to Distinguish Apathy From Depression in Alzheimer's Disease and Related Dementias.: Early detection of Alzheimer's disease (AD) and related dementias in the elderly is critical for improving treatment methods and is a necessary component for improving public health interventions. One of the earliest and most common behavioral syndromes of AD is apathy and is associated with executive dysfunction. Apathy in AD is often misdiagnosed as depression due to an overlap in symptoms. Studies that have found depression to be associated with executive dysfunction have not always controlled for the presence of apathy. The Geriatric Depression Scale (GDS) is a widely used instrument designed to assess depression in the elderly. This study utilized the GDS and a set of standard neuropsychological instruments to investigate the relationship between apathy, depression, and executive functions in individuals with AD and related dementias. The first objective of this study was to determine if apathy has a greater impact on executive functions compared to depression in AD and related dementias. The second objective was to determine the effectiveness of the GDS as a screen for apathy. The results of the analyses did not support the hypotheses. However, exploratory analyses suggested a possible non-linear relationship with apathy and various levels of dementia severity. Exploratory analysis also suggested mean levels of endorsement for apathy varied by diagnosis. Further research is warranted to investigate this relationship and the GDS endorsement patterns for caregivers regarding their impression of the demented individual.
Theoretical and Practical Record of the Making of the Documentary Film, A Native American Dream: This textual record of the making of the social issue documentary film A Native American Dream examines theoretical and practical considerations of the filmmaker during the pre-production, production, and post-production stages. It also examines the disciplines of anthropology and ethnography in terms of modern documentary filmmaking and evaluates the film within these contexts.
Perceptions of agency: Beliefs of four adolescent girls in high school as revealed through literature discussions.: Published research suggests that cultural practices and institutional structures influence adolescent girls' engagement and achievement in school. This study was an attempt to further investigate that claim by describing the perceptions of agency held by four adolescent girls in high school. Members of the same English class, the girls volunteered to participate in three lunchtime meetings to discuss Evelyn Coleman's (2001) Born In Sin. Analysis of classroom observations, transcripts of audio recordings of the book discussions, and individual interviews yielded a more precise definition of agency than those used in previous research, including a view of agency as dialogic. In addition, four major themes describe these girls' agentic moves: (1) a temporal orientation, which connects the past, present, and future; (2) responsibility for positive and negative events; (3) strategic decision making; (4) negotiating with people in power. Implications of this study inform both teaching decisions and future research related to adolescent girls.
The Politics of Translation: Authorship and Authority in the Writings of Alfred the Great: The political implications of the OE prose translations of King Alfred (849-899) are overlooked by scholars who focus on the literary merits of the texts. When viewed as propaganda, Alfred's writings show a careful reshaping of their Latin sources that reaffirms Alfred's claim to power. The preface to Pastoral Care, long understood to be the inauguration of Alfred's literary reforms, is invested with highly charged language and a dramatic reinvention of English history, which both reestablishes the social hierarchy with the king more firmly in place at its head and constructs the inevitability of what is actually a quite radical translation project. The translations themselves reshape their readers' understanding of kingship, even while creating implicit comparison between Alfred and the Latin authors.
Pediatric feeding disorders: Efficacy of multidisciplinary inpatient treatment of gastrostomy tube dependent children.: Efficacy of multidisciplinary inpatient treatment of feeding disordered children was sought through retrospective chart review of 40 G-tube dependent children ages 22 months to 7 years. Premature births were 55% of the sample ranging from 23 to 36 weeks gestation. The majority of co-occurring medical conditions included congenital anomalies (50%), gastroesophageal reflux disease (25%) and chronic lung disease (25%). Treatment effect analyzed from pre and post treatment measures of oral and G-tube caloric intakes resulted in a significant difference from admission to discharge for both oral intake, t (39) = 5.76, p < 0.001, d = 1.02, and G-tube dependency, t(39) = 10.94, p < 0.001, d = 2.03 with both showing strong treatment effects. Results indicated a highly reliable and valid method of treating severe pediatric feeding disorders.
Women's erotic rape fantasies.: This study evaluated the rape fantasies of a female undergraduate sample (N = 355) using a sexual fantasy checklist, a sexual fantasy log, a rape fantasy scenario presentation, and measures of personality. Results indicated that 62% of women have had a rape fantasy. For these women, the median rape fantasy frequency was about four times per year, with 14% of participants reporting that they had rape fantasies at least once a week. Further, rape fantasies exist on a continuum between erotic and aversive, with 9% completely aversive, 45% completely erotic, and 46% both erotic and aversive. Women who are more erotophilic, open to fantasy, and higher in self-esteem tended to have more frequent and erotic rape fantasies than other women. The major theories that have been proposed to explain why women have rape fantasies were tested. Results indicated that sexual blame avoidance and ovulation theories were not supported. Openness to sexuality, sexual desirability, and sympathetic activation theories received partial support.
Identifying learn units in a naturalistic training program for children with autism and their families.: Behavior analysts have proposed a primary measure, the "learn unit," to evaluate educational effectiveness. Past research has indicated this is a useful approach. The benefits of "learn units" may also apply to family interventions in autism. The current analysis evaluated the rates of learn units in a naturalistic parent-training program to determine if (1) definitions of learn units previously described in the literature can be reliably applied to family interventions and (2) an increased number of learn units correlate with increased child responding and attainment of child and family goals. Results from the current analysis demonstrated that the rate of learn units increased from baseline to training for all parent-child dyads and the percent of correct child responses increased for all children. Teaching parents the components of effective education may increase the quantity and quality of interventions for children diagnosed with autism.
Comparison of Client Attendance, Attrition, and Outcomes in 2 Class System Packages.: Using the principles of systems analysis as a guide, this study compared two class schedule formats used by Behavior Management and Parenting Services (BMAPS) in order to address the following research questions: 1) What effects do 2 different class formats have on student attrition and appointment keeping? 2) What effects do 2 different class formats have on student outcomes on a pre and posttest assessment? 3) What effects do 2 different class formats have on staff procedures? BMAPS provides parent education to individuals referred by Child Protective Services. The current research included approximately 200 referred clients with an appointment or class scheduled with BMAPS between January 1, 2006 and September 22, 2007. Data was collected by reviewing client files for class attendance and performance records. Results of this study allow BMAPS to enlist the class format that is correlated with better attrition rates and client outcomes.
Personality and the prediction of outcome following rehabilitation in persons with acquired brain injuries: The Millon Behavioral Medicine Diagnostic (MBMD).: Neuropsychological rehabilitation following acquired brain injury is increasingly recognized as essential with the advancements in research evidence of its effectiveness, particularly as current estimates of disability following the most common forms of brain injury (traumatic brain injury and cerebrovascular accident) are so high. Improvements in predictive capabilities of researchers and clinicians are paramount in designing effective interventions. As many variables associated with outcome following brain injury are not controllable (e.g. severity of the injury, age, education), it is essential that rehabilitation programs design interventions to target those variables that are susceptible to amelioration. While personality factors have been shown to affect outcome in other medical illnesses, only a few studies have examined the influence of personality on outcome following neurorehabilitation for acquired brain injury. The results of these studies have been mixed. This study used the Millon Behavioral Medicine Diagnostic (MBMD) to predict outcome as measured by the Mayo-Portland Adaptability Index (MPAI-4) following brain injury rehabilitation in a heterogeneous sample of persons with acquired brain injuries (N = 50). It was hypothesized that specific coping styles scales from the MBMD (Introversive, Dejected, Oppositional), which are based on Millon's personality system, would predict outcome. Results indicated that both the Introversive and Oppositional coping styles scales accounted for significant amounts of variance in outcome beyond that accounted for by the severity of the injury alone (p < .001). In both cases, individuals with mild/moderate-moderate/severe limitations following completion of the rehabilitation program had significantly higher scores on the Introversive and Oppositional coping compared to individuals with more successful outcomes. The hypothesis that a dejected coping style would predict outcome was not supported. Implications for rehabilitation are discussed in the context of Millon's personality system.
A Stranger Amongst Strangers: An Analysis of the Freedmen's Bureau Subassistant Commissioners in Texas, 1865-1868: This dissertation is a study of the subassistant commissioners of the Freedmen's Bureau in Texas from late 1865 to late 1868. Its focus is two-fold. It first examines who these men were. Were they northern born or southern? Did they own slaves? Were these men rich, poor, or from the middle-class? Did they have military experience or were they civilians? How old was the average subassistant commissioner in Texas? This work will answer what man Freedmen's Bureau officials deemed qualified to transition the former slave from bondage to freedom. Secondly, in conjunction with these questions, this work will examine the day-to-day operations of the Bureau agents in Texas, chronicling those aspects endemic to all agents as well as those unique to certain subdistricts. The demand of being a Bureau agent was immense, requiring long hours in the office fielding questions and long hours in the saddle inspecting subdistricts. In essence, their work advising, protecting, and educating the freedmen was a never ending one. The records of the Freedmen's Bureau, both the records for headquarters and the subassistant commissioners, serve as the main sources, but numerous newspapers, Texas state official correspondences, and military records proved helpful. Immense amounts of information arrived at Bureau headquarters from field personnel. This work relies heavily on reports and letters in the Bureau agents' own words. This dissertation follows a chronological approach, following the various Bureau administrations in Texas. I believe this approach allows the reader to better glimpse events as they happened.
An Analysis of Established Terrorist Identity in Political and Military Wings of Turkish Hizbullah: The influence of the role identity expectations of Turkish Hizbullah's leadership on actual members' terrorist identities was documented in this dissertation. This study explored the leadership's identity expectations from members through content analyses of four books written by major figures of Hizbullah. Those books were selected following comments of the literature and expert suggestions. Eleven identity features stood out. These content analyses also revealed that leadership had different expectations from political wing members and military wing members. The following six identity features were listed as expected more from military wing members: belief in jihad and resistance, desire for martyrdom, embracing the hierarchical structure, depersonalization, hatred against enemies of God, and aloneness. Whilst cemaat (religious congregation), being religiously educated, patience (gradualism), dedication to a Muslim brotherhood, and being politically active were listed as expected identity attributes of political wing members. Qualitative analyses investigated these identity features using the available literature and 144 handwritten reports of actual Hizbullah members. To confirm the findings of content and qualitative analyses, quantitative analyses were conducted on the relatively representative sample (144 reports). The results of cross-tabulation and logistic regression demonstrated that two (out of 6) military wing and two (out of 5) political wing identity expectations were not manifested on actual members' Hizbullah identities.
The skazki (fairy tales) of Nikolai Medtner: The evolution and characteristics of the genre with compositional and performance aspects of selected fairy tales.: The compositional language of Russian composer-pianist Nikolai Medtner (1880-1951) demonstrates an evolution of the traditional forms and harmony. Following the classical and romantic traditions, Medtner's compositional technique reveals his individual and original approaches to form and harmony. The unique architectonic in his works is achieved through particular tonal-harmonic juxtapositions of the sections, the frequent prevalence of the monothematic principle, the increased role of the developmental material in the exposition, and contrapuntal combination of themes. Harmonic vocabulary is characterized by chromatic harmony, altered dissonant chords, augmented triads, complex chains of modulations, and usage and combination of modes and octatonic scale. Counterpoint is of great importance toward understanding the chord progression found in his music. Skazki (fairy tales) are pieces in small form, such as preludes, or novelettes; they hold an important place in Medtner's oeuvre. The fairy tale genre is associated with many artistic traditions, including Russian folk art. Medtner's 38 fairy tales, varied in imagery and character, were composed during different periods of his life. The evolution of the genre is seen in form and harmonic language. The lyrical, subjective mood of the fairy tales of the earlier period, such as op. 8, op. 9 and op. 14, evolve into large-scale works, such as fairy tales op. 20 and op. 35. In his later years, in fairy tales from op. 42, Medtner imbues the form with a greater clarity of expression, a tendency to move toward simpler musical expression, and an expanded use of thematic Russian folklore sources, including more definite ties with song and dance genres.
String student self-efficacy and deliberate music practice: Examining string students' musical background characteristics, self-efficacy beliefs and practice behaviors.: This study examined the musical background characteristics, self-efficacy beliefs, and practice behaviors of string students auditioning for an all-region orchestra in one large South-Central district. Purposes of the study were: (1) to describe the musical backgrounds and self-efficacy beliefs of high school string students, (2) to measure the relationship between self-efficacy scores and performance achievement, and (3) to describe the practice behaviors and thoughts of high and low self-efficacy string students. Questionnaires were given to 101 high school string students; 65 competed in all-region orchestra. Descriptive data from the questionnaire revealed information such as how many took private lessons and that those who did tended to have a higher sense of perceived self-efficacy in relation to playing their string instruments. Other descriptive items asked questions such as whether or not students started in public school and how much they practiced outside of orchestra. The relationship of summed self-efficacy scores to a competition ranking was found to be statistically significant and inverse. For all string participants (n=65) Spearman's rho was, rs= -.37, (p=.001) with 14% of the variance explained (r2 =.14). This inverse relationship documents the linear trend for students with better rankings (lower ranking numbers) to also tend to have higher self-efficacy scores. Observation and interview data of 8 higher and 8 lower self-efficacy sub-group students were also analyzed. The higher self-efficacy sub-group students tended to use more cognitive practice strategies, while the lower self-efficacy sub-group tended to use dissimilar and less advanced strategies. Understanding string students' musical background experiences and characteristics and the possible relationship self-efficacy may have with practice and achievement could benefit certain students. Helping these students gain a higher sense of perceived self-efficacy in their musical endeavors, or obtain certain characteristics that successful students share, could possibly enable them to develop and understand more complex practice …
Children of Teenage Mothers: School Readiness Outcomes and Predictors of School Success.: The purpose of this study was to examine the effects of teenage motherhood on the school readiness, literacy skills, and parental involvement of children participating in the Home Instruction for Parents of Preschool Youngsters (HIPPY) early intervention program, as well as make recommendations for optimal outcomes. Study children were participants in HIPPY at five diverse, urban school districts. Using a mixed method design, this study examined the results of quantitative measures of children's school readiness, literacy skills, and parent involvement along with qualitative data collected through mothers' responses to two, open-ended questions related to their satisfaction with HIPPY. According to results of independent samples t-test, mean scores on school readiness and parent involvement measures were not statistically significantly different for the children of teenage mothers and the children of traditional age mothers. However, there were moderate effect sizes for parent involvement and physical development indicating some practical significance. Chi-square results of literacy skills indicated that the children of teenage mothers were almost twice as likely [c2 (1, N = 36) = 4.21, p < .05] to have literacy skills that were "not on grade level" according to scores on the TPRI/Tejas. Descriptive discriminant analysis (DDA) indicated that the multivariate relationship of the four parent involvement variables statistically significantly contributed to whether children born to teenage mothers had literacy skills on grade-level, but it was not significant for the children of traditional-age mothers. DDA analysis conducted on the school readiness variables did not yield any significant results. In addition, odds ratios conducted between literacy level and each of the parent involvement and school readiness variables indicated an increased probability of a child's literacy skills being on grade level when scores were high, but these increases were not statistically significant. While there were differences in literacy skills, teen mothers indicated, through their …
Characteristics of Preservice Teachers Learning Parent Involvement Practices.: Numerous models of IS success and technology acceptance their extensions have been proposed and applied in empirical. This study continues this tradition and extends the body of knowledge on the topic of IS success by developing a more comprehensive model for measuring IS success and technology acceptance within a government organization. The proposed model builds upon three established IS success and technology acceptance frameworks namely the DeLone and McLean (2003), Venkatesh et al.'s (2003) unified theory of acceptance and use of technology (UTAUT), and Wixom and Todd (2005). The findings from this study provide not only a comprehensive IS success assessment model but also insights into whether and how IS success models are influenced by application variables as applied within a government organization. Exploratory factor analysis and confirmatory factor analysis were performed for instrument refinement and validity test of the existing and proposed models. Using data from employees of a local government municipal, the comprehensive model explained 32 percent variance. Four of the hypothesis were fully supported five were not supported, and four were partially supported. In addition, the results suggest that behavioral intention may not be the best predictor of technology acceptance in a mandatory environment.
Information systems success and technology acceptance within a government organization.: Numerous models of IS success and technology acceptance their extensions have been proposed and applied in empirical. This study continues this tradition and extends the body of knowledge on the topic of IS success by developing a more comprehensive model for measuring IS success and technology acceptance within a government organization. The proposed model builds upon three established IS success and technology acceptance frameworks namely the DeLone and McLean (2003), Venkatesh et al.'s (2003) unified theory of acceptance and use of technology (UTAUT), and Wixom and Todd (2005). The findings from this study provide not only a comprehensive IS success assessment model but also insights into whether and how IS success models are influenced by application variables as applied within a government organization. Exploratory factor analysis and confirmatory factor analysis were performed for instrument refinement and validity test of the existing and proposed models. Using data from employees of a local government municipal, the comprehensive model explained 32 percent variance. Four of the hypothesis were fully supported five were not supported, and four were partially supported. In addition, the results suggest that behavioral intention may not be the best predictor of technology acceptance in a mandatory environment.
Affective and cognitive components of job satisfaction: Scale development and initial validiation.: Job satisfaction is one of the most commonly studied variables in the organizational literature. It is related to a multitude of employee-relevant variables including but not limited to performance, organizational commitment, and intent to quit. This study examined two new instruments measuring the components of affect and cognition as they relate to job satisfaction. It further proposed including an evaluative (or true attitudinal) component to improve the prediction of job satisfaction. Results provide some evidence of both two and three factor structures of affect and cognition. This study found minimal support for the inclusion of evaluation in the measurement of job satisfaction. Affect was found to be the single best predictor of job satisfaction, regardless of the satisfaction measure used. Further development is needed to define the factor structures of affect and cognition as well as the role of these factors and evaluation in the prediction of job satisfaction.
Factors influencing horizontal cracking in continuously reinforced concrete pavements (CRCP).: This research presents the results on an experimental investigation to identify the significant factors influencing horizontal cracking in continuously reinforced concrete pavements (CRCP). An in-depth analysis of the microstructure, morphological characteristics of the interfacial transition zone (ITZ) and the observation of cracking using the environmental scanning electron microscope (ESEM) was done. Characterization of oxides using Fourier transform infrared spectroscopy (FTIR) and electron dispersive x-ray spectroscopy (EDS) was also performed. Water to cement ratio (w/c) and rebar temperature had a significant influence on the rebar-concrete bond strength. The 28-day shear strength measurements showed an increase in rebar-concrete bond strength as the water to cement ratio (w/c) was reduced from 0.50 to 0.40. There was a reduction in the peak pullout load as the temperature increased from 14oF to 252oF for the corroded and non-corroded rebar experiments. The corroded rebar pullout test results showed a 20-50 % reduction in bond strength compared to the non-corroded rebars. FTIR measurements indicated a presence of lepidocrocrite (γ -FeOOH) and maghemite (γ -Fe2O3) on the ITZ. ESEM images showed the existence of microcracks as early as three days after casting with the bridging of these cracks between coarse aggregate locations in the interfacial zone propagating through the mortar.
Pride and sexual friendship: The battle of the sexes in Nietzsche's post-democratic world.: This dissertation addresses an ignored [partly for its controversial nature] aspect of Nietzschean philosophy: that of the role of modern woman in the creation of a future horizon. Details of the effects of the Enlightenment, Christianity and democracy upon society are discussed, as well as effects on the individual, particularly woman. After this forward look at the changes anticipated by Nietzsche, the traditional roles of woman as the eternal feminine, wife and mother are debated. An argument for the necessity of a continuation of the battle of the sexes, and the struggle among men and women in a context of sexual love and friendship is given. This mutual affirmation must occur through the motivation of pride and not vanity. In conclusion, I argue that one possible avenue for change is a Nietzschean call for a modern revaluation of values by noble woman in conjugation with her warrior scholar to bring about the elevation of mankind.
In justice to our Indian allies: The government of Texas and her Indian allies, 1836-1867.: Traditional histories of the Texas frontier overlook a crucial component: efforts to defend Texas against Indians would have been far less successful without the contributions of Indian allies. The government of Texas tended to use smaller, nomadic bands such as the Lipan Apaches and Tonkawas as military allies. Immigrant Indian tribes such as the Shawnee and Delaware were employed primarily as scouts and interpreters. Texas, as a result of the terms of her annexation, retained a more control over Indian policy than other states. Texas also had a larger unsettled frontier region than other states. This necessitated the use of Indian allies in fighting and negotiating with hostile Indians, as well as scouting for Ranger and Army expeditions.
Carl Sandburg's Timeless Prairie: Philip Wharton's Song Cycle, The Prairie Sings: The connection of music and verse evident in the work of American poet, Carl Sandburg, is a topic that has received inadequate attention. Much preexisting research has focused on Sandburg's work with The American Songbag anthology; however little has been written about music composers' settings of his verse. The relevance of Sandburg's work as a poet has faded in today's society; the rural prairie subject matter and his poetic style are deemed archaic in an ever-evolving mechanistic society. Philip Wharton, a native of Sandburg's Midwest prairie, composes to create an evocative and image-laden world for the hearers of his music. This is what creates a semblance between both artists' works. This paper makes a connection between the work of the 20th century prairie poet and a current, 21st century American composer's musical setting of Sandburg's verse. Both artists are connected not only geographically, but also in their approach to an accessible art form for their audience. Negating current compositional trends and using text from Sandburg's poetry collections, Chicago Poems and Cornhuskers, Wharton melds the text into his evocative, imagistic musical language in his song cycle, The Prairie Sings. Using examples from the five movements of the cycle, I show the dependent relationship of verse and music. An in-depth analysis of the connection of poetry and music in each of the five movements of the cycle is contained in the paper. An additional connection in the dynamic interplay of the vocal line and piano accompaniment, the two "narrators" of the cycle, is also discussed. The resulting research points to an aspect of a creation of a regional American "sound, " reminiscent of trends of nationalism in the 19th and 20th century in art, literature and music.
Reassessing the Role of Anxiety in Information Seeking: Previous research of the theory of Affective Intelligence holds that anxiety in individuals causes learning behavior. If people are anxious they will actively seek new information. This new information gathered while anxious will cause each individual person to cease acting habitually and begin acting in a manner in line with rational choice models. This thesis addresses three hypotheses; (1) that people who feel anxiety engage in greater information seeking behavior and (2) when people feel anxious they will use information sources that are readily available and efficient to use and (3) anxious individuals will turnout to vote more often than those who are not anxious. I began with the replication of the original research methods of Marcus and MacKuen (1993) and Marcus, Neuman and MacKuen (2000). I then tested hypothesis 1 using new measurements of anxiety in order to address the concerns originally posited by Ladd and Lenz (2008) and Valentino et al. (2008). My final test of hypothesis 1 used revised measurements of anxiety and information derived from 2000-2002 NES Panel data, much in the same manner as Marcus, Neuman and MacKuen (2000). I then tested hypothesis 2 using the same 2000-2002 NES Panel data and an information source change variable. I tested my final hypothesis using pooled NES data from 1984, 1988 and 2000. My findings suggest that as Affective Intelligence predicts, people who feel anxious do tend to seek information. Moreover, when anxious, people will use readily available and efficient information sources. My final finding suggests that although people tend to seek information when anxious this does not necessarily translate into greater participation. Finally, I conclude that the theory of Affective Intelligence is generally correct, but, further research using methods that can better demonstrate the causal direction needs to be undertaken to fully validate Affective Intelligence and …
The Effects of the Recapture Provision of Senate Bill 7 of 1993 Upon the Quality of Schools: an Analysis of Perceptions of Administrators in Both Chapter 41 and Chapter 42 Schools.: The purpose of this 4-case study was to determine the significance of the effects of the recapture legislation in Texas upon the quality of schools as perceived by administrators in participating school districts, including those surrendering funds (Chapter 41) and those receiving funds (Chapter 42). The recapture provision requires districts above a designated level of property wealth to surrender excess funds to be appropriated to districts with property wealth below a designated level. The study solicited administrators’ perceptions in both district types as to whether the changes in funding have significantly affected the quality of their schools. Using University Scholastic League classifications as a guideline for size, 2 Chapter 41 districts, and 2 Chapter 42 districts, 1 small and 1 large of each type, were selected to participate. Variables included 5 indicators of schools quality that are repeatedly mentioned in literature concerning effective schools: curriculum, climate, leadership, facilities, and safety and security. A review of literature included the historical development of public school finance systems as well as studies of the effects of efforts to equalize funding upon both the financial health and academic performance of schools. A weak link or no link between funding systems and student performance or financial health was indicated. This study supported these conclusions with both Chapter 42 districts; however, there was a discrepancy between the perceptions of administrators in the two Chapter 41 districts, indicating a need for further study. The unique aspects of this study are that it solicited directly the perceptions of acting administrators and that it included administrators in districts receiving funds to determine how those funds are being used and whether they have a significant effect upon school quality.
Megatrends in Higher Education: Utilizing the theory of John Naisbitt's 1982 Megatrends, this study identifies eight trends for the future of higher education using content analysis of generalized print media reports for three bell-wether states. For the period of 2001-2005, generalized reporting for three newspapers, the Los Angeles Times from Los Angeles, CA, the Miami Herald from Miami, FL, and the Denver Post from Denver, CO, included over four thousand articles and covered 21 primary topics and over 200 secondary topics. Eight trends emerge from the content analysis. Trend 1, from the ivory tower to the public domain, identifies increasingly critical public scrutiny of higher education standards and curricula. Fight or flight, Trend 2, reveals more consistent no-tolerance policies for student behavior. Trend 3, scholar to celebrity, reveals an increasingly public role for university presidents. Academic freedom to academic flexibility, Trend 4, identifies a tightening of academic freedom policies for university staff and faculty. Trend 5, pay now, learn later, focuses on increased popularity of pre-paid and tax free plans for saving college tuition. Fraternity party to fraternity accountability, Trend 6, identifies increased scrutiny of Greek organizations and Greek life within the university environment. Trend 7, tenure to temporary, reflects the growing trend of hiring more part-time faculty rather than hiring faculty for tenure track positions or full-time instructor jobs. Lastly, campus to cyberspace, Trend 8, identifies the continued success of online instruction at the university level.
Reducing the risk of disordered eating among female college students: A test of alternative interventions.: The purpose of this study was to test the effectiveness of a cognitive-dissonance based intervention in reducing disordered eating attitudes and behaviors. The intervention program created dissonance through discussion, exercises, and homework aimed at addressing and countering internalized sociocultural pressures, beliefs and values about women's bodies, attractiveness, and worth in the U.S. Seventy-seven female undergraduates were randomly assigned to one of four conditions: cognitive-dissonance, combined cognitive-dissonance, healthy weight placebo control, and wait-list control To determine effectiveness of the intervention, MANCOVA procedures were used, with Time 1 scores serving as the covariate. Overall, the women who received the dissonance based interventions produced the strongest effects among measures assessing sociocultural pressures, internalization, and body dissatisfaction in comparison to the control group, and experienced significant reductions in dieting behaviors and bulimic symptoms over the course of the study, suggesting that the creation of dissonance via the intervention assisted the women in reducing eating disorder risk factors.
Extended performance techniques and compositional style in the solo concert vibraphone music of Christopher Deane.: Vibraphone performance continues to be an expanding field of music. Earliest accounts of the presence of the vibraphone and vibraphone players can be found in American Vaudeville from the early 1900s; then found shortly thereafter in jazz bands as early as the 1930s, and on the classical concert stage beginning in 1949. Three Pieces for Vibraphone, Opus 27, composed by James Beale in 1959, is the first solo concert piece written exclusively for the instrument. Since 1959, there have been over 690 pieces written for solo concert vibraphone, which stands as evidence of the popularity of both the instrument and the genre of solo concert literature. Christopher Deane has contributed to solo vibraphone repertoire with works that are regarded as staples in the genre. Deane's compositions for vibraphone consistently expand the technical and musical potential of the instrument. Performance of Deane's vibraphone works requires a performer to utilize grips and specific performance techniques that are departures from standard performance practices. Many of the performance techniques needed to successfully execute these pieces are not routinely found in either percussion pedagogy courses or performance ensemble situations. As a result, most percussionists are not familiar with these techniques and will require additional assistance, instruction, or demonstrations. The impetus of this document is to present explanations and solutions for performance areas that require extended performance techniques, to offer recommendations on the creation, choosing, and manipulating of special implements, and to propose varied choices related to artistic interpretation of three of Deane's vibraphone pieces: Mourning Dove Sonnet (1983), The Apocryphal Still Life (1996), and Dis Qui Etude (2004).
Carl Orff's Carmina Burana: A Comparative Study of the Original for Orchestra and Choruses with the Juan Vicente Mas Quiles Wind Band and Chorus Arrangement.: The 1994 publication of a new version of Carl Orff's Carmina Burana, arranged for winds, percussion and choruses by Juan Vicente Mas Quiles, created new possibilities for the performance of Orff's monumental work. This dissertation serves as a guide to the study and performance of the Mas Quiles arrangement of Carmina Burana. Chapter One presents a brief discussion of Carl Orff and his Carmina Burana, followed in Chapter two by a short discussion of Mas Quiles' and the other significant transcriptions and arrangements of Carmina Burana, Chapter three contains a review of the literature pertinent to the study Carmina Burana. In Chapter Four a detailed examination and comparison of the original Orff score with the Mas Quiles arrangement provides a framework with which the conductor may study and compare the two scores in preparation for a performance of the Mas Quiles arrangement. The scoring of the Mas Quiles arrangement is masterful in that the arrangement so closely maintains the textural, musical and aesthetic integrity of the work. The Mas Quiles version includes all of the movements, and all of the original elements: choruses, soloists and orchestral parts are preserved intact. The only substantive change is the judicious use of winds in place of the orchestral string parts. By comparison and analysis of Mas Quiles scoring techniques with the Orff original, the author concludes that the Mas Quiles arrangement is a viable and unique alternative to the Orff original and highly worthy of study and performance by conductors of advanced level ensembles.
Heart rhythm variability in persons with chronic pain.: The present study evaluated the utility of heart rhythm coherence (HRC) feedback to reduce the reported pain intensity of patients enrolled in a multimodal pain management program. Participants were recruited and assigned to a usual treatment group (UT) or a heart rhythm coherence feedback group (UT+HRC). It was hypothesized that UT+HRC participants who achieved heart rhythm coherence would report a reduction of pain intensity, as measured by the McGill Pain Inventory. For those whose pain intensity decreased, it was also expected that their self reported levels of depression as measured by the Beck Depression Inventory-Second Edition and state anger as measured by the State Trait Anger Inventory would decrease. It is also hypothesized that with a reduction in pain levels, anger, and depression, blood pressure would also decrease among those who had high blood pressure prior to the intervention. Multivariate analyses of variance (MANOVA) were used to investigate the relationship between treatment condition, coherence status and pain levels. A series of independent t-tests were utilized to investigate the change in pain, depression, and state anger from baseline to posttest, followed by Pearson product moment correlation coefficients on difference scores to understand the relationship between the outcome variables for Hypothesis 2. Standard multiple regression analyses were computed using difference scores to determine if the outcome measures were significant predictors of systolic blood pressure and diastolic blood pressure. Results indicated a failure to reject the null with regard to hypothesis one. No relationship between treatment assignment, coherence status or pain levels were found. Hypothesis 2 was partially supported. Although there was a positive significant relationship between depression and anger when utilizing difference scores, these affective measures were not related to difference scores on either pain measure. In regard to Hypothesis 3, there was also a failure to reject the null. None of …
Child Soldiers and Intrastate Armed Conflicts: An Analysis of the Recruitments of Child Soldiers in Civil Wars Between 2001 and 2003.: This thesis examines why some governments and rebel organizations but not others recruit children to be child soldiers. The theory posits that if a country fights in a civil war of long duration, armed groups are more likely to recruit children as soldiers. I find that the probability of child soldier recruitment increases when a country experiences following conditions: a longer duration of civil war, a large proportion of battle deaths, a large number of refugees, a high infant mortality rate, and the presence of alluvial diamonds. An increase in education expenditures and civil liberties would decrease the probability of child soldier recruitments.
Central American Media: A Comparative Study of Media Industries in Guatemala, Nicaragua, Honduras, El Salvador, and Costa Rica.: The five countries that lie on the isthmus connecting North and South America have endured a past of colonialism, civil war, and natural disaster. As these countries evolve in the 21st century, growing economies and political peace provide a promising outlook for the citizens of these nations. The media industries in these nations have varying levels of development which are explored in this thesis. Using Michael Porter's 1990 framework and a case study methodology, this thesis explores the differences and similarities of media industries in Guatemala, El Salvador, Honduras, Nicaragua and Costa Rica, and what may be done to ensure future success in an increasingly global world.
Twinmates: Twinmates is an inside look at the unique and unusual appeal of border politics in Laredo, Texas through the point of view of identical twin brothers-- A. Jaime Mendoza and B. Javier Mendoza. The documentary chronicles the Mendoza twins for a period of six years as they switch political parties, in order to get elected (Republicans turn Democrats), and use that political exposure to expand their janitorial company to the metropolitan cities of Dallas and Austin. In addition to the Mendoza twins' business and politics, the documentary also captures entertaining interactions with family and friends.
Clestrinye [El Carnaval del Perdón]: Traditional Rituals in Intermedia Composition.: In Part I of this thesis, I examine the use of Latin American rituals, ceremonies, and traditional folklore as conceptual and compositional material; studying and re-contextualizing concepts, cultures, and ideologies, and introducing them to foreign audiences. I explore issues such as laptop improvisation, interaction with other performance forces, and the utilization of the social elements of non-western celebrations, as explored in Clestrinye, a work for live and fixed electronics, mixed ensemble, dancers, and painters.
Dallas, Poverty, and Race: Community Action Programs in the War on Poverty: Dallas is a unique city whose history has been overshadowed by its elite. The War on Poverty in Dallas, Texas, has been largely overlooked in the historical collective. This thesis examines the War on Poverty, more specifically, Community Action Programs (Dallas County Community Action Committee) and its origin and decline. It also exams race within the federal program and the push for federal funding among the African American and Mexican American communities. The thesis concludes with findings of the politicization of the Mexican American community and the struggle with African Americans for political equality.
IT Offshoring Success: A Social Exchange Perspective: Spending by U.S. companies in offshore IT services continues at unprecedented levels despite a high failure rate. This study fills a gap in the existing literature by examining the client-vendor offshoring relationship through the theoretical lens of social exchange theory at the organizational level of analysis from the client's perspective. Social exchange theory focuses on the exchange of activities between two parties, whether they are individuals or companies and was used as a basis for examining the client and vendor relationship. Variables were identified by a review of the literature primarily from IT outsourcing and offshoring but also from general IT, marketing, sociology and organizational science literature. Data was collected using a field survey of Fortune 500 CIOs representing a population of organizations at the forefront of the offshoring phenomenon. The survey instrument was developed based on the adaptation of previously validated scales. Hypotheses regarding the correlations between social variables such as trust, communication, dependence, power, shared values and offshoring success were tested using Spearman's rho correlation. Seven of the hypotheses were supported, four hypotheses were not supported and one hypothesis was deemed not testable due to lack of information.
Strategic Factors Influencing the Issuance and Duration of Executive Orders: Executive orders are a significant source of presidential power although scholars disagree on the nature of that power. It has been argued that executive orders are an indication of a president's failure to persuade others to act as he desires; others contend that executive orders offer "power without persuasion." This dissertation introduces the conditional model of executive order issuance and duration in order to offer a synthesis to these competing views, and to offer a better understanding of the opportunities and constraints faced by the president when choosing to act unilaterally through executive orders. The conditional theory holds that both the issuance and duration of executive orders is a function of the president's ideological proximity to Congress and the Supreme Court, and the availability of fresh policy space.
Expression analysis of the fatty acid desaturase 2-4 and 2-3 genes from Gossypium hirsutum in transformed yeast cells and transgenic Arabidopsis plants.: Fatty acid desaturase 2 (FAD2) enzymes are phosphatidylcholine desaturases occurring as integral membrane proteins in the endoplasmic reticulum membrane and convert monounsaturated oleic acid into polyunsaturated linoleic acid. The major objective of this research was to study the expression and function of two cotton FAD2 genes (the FAD2-3 and FAD2-4 genes) and their possible role in plant sensitivity to environmental stress, since plants may increase the polyunsaturated phospholipids in membranes under environmental stress events, such as low temperature and osmotic stress. Two FAD2 cDNA clones corresponding to the two FAD2 genes have been isolated from a cotton cDNA library, indicating both genes are truly expressed in cotton. Model yeast cells transformed with two cotton FAD2 genes were used to study the chilling sensitivity, ethanol tolerance, and growth rate of yeast cells. The expression patterns of the two FAD2 genes were analyzed by reverse transcription polymerase chain reactions (RT-PCR) and Western blot analyses in cotton plants under different treatment conditions. The coding regions of both FAD2 genes were inserted downstream from the CaMV 35S promoter in the pMDC gateway binary vector system. Five different FAD2/pMDC constructs were transformed into the Arabidopsis fad2 knockout mutant background, and multiple potential transgenic Arabidopsis plant lines harboring the cotton FAD2 genes were generated. The cotton FAD2 genes were amplified by the polymerase chain reaction (PCR) from the genomic DNAs isolated from the transgenic Arabidopsis T1 plant lines. Complementation of the putative transgenic Arabidopsis plants with the two cotton FAD2 genes was demonstrated by gas chromatography analyses of the fatty acid profiles of leaf tissues. The cellular localization of cotton FAD2-4 polypeptides with N-terminal green fluorescence protein (GFP) was visualized by confocal fluorescence microscopy. The phenotype of transgenic Arabidopsis plants transformed with the cotton FAD2-4 gene was compared to Arabidopsis knockout fad2 mutant plants and wild …
Increasing activities and interests in a child dually diagnosed with PDD-NOS and DS.: Expanding interests may be a behavioral cusp, resulting in widespread changes across skills, and therefore is particularly relevant in intervention programs for children with autism. Little research has addressed directly increasing the diversity of activities and interests for this population. This study describes a program developed to increase activities and interests in a girl dually-diagnosed with pervasive developmental disorder (PDD-NOS) and Downs syndrome (DS). A multiple-baseline design across stimuli was employed to evaluate the program. The results show that the program increased number of total and different toy interactions. No effects were observed for overall duration of toy interactions. Results are discussed in relation to play skill instruction and preference assessment literature, the cusp, and autism intervention programs.
